Ectoin Hydro-Barrier Serum | The INKEY List
Hydrates whilst supporting and strengthening the skin’s barrier
Replenishing your hydration whilst simultaneously repairing your barrier is essential for protecting against winter dryness and moisture loss. Our Ectoin Hydro-Barrier Serum has been uniquely formulated with ingredients that work synergistically to provide deep, multi-level hydration, helping to lock in moisture and shield the skin from environmental aggressors.
2% Ectoin: Known as an extreme protector, Ectoin acts as a natural hydrator and skin cell stabilizer, helping to prevent winter-induced dehydration, calm irritation, and reinforce barrier strength for skin that stays soft, smooth, and comfortable.
Multi-Molecular Hyaluronic Acid: Helps restore the protective skin barrier from the outside in, enabling it to retain moisture more effectively—even in cold, dry air.
Whether you're looking for a hydrating serum for winter-parched skin or a lightweight layer of moisture to keep skin balanced, with continued daily use, this serum visibly improves 5 signs of a compromised skin barrier: dullness, dryness, redness, flakiness, and slackness. The INKEY List’s Ectoin Serum has a lightweight texture that melts into the skin, delivering instant, non-tacky hydration—perfect for layering under your winter skincare and makeup routine.
